Among the independent risk factors affecting the postoperative tumor‐free survival (RFS) of HCC patients, in addition to the above factors, an AFP ≥ 400 ng/mL and a GGT > 50 U/L were also included, which corresponded to an HR of 1.430, a 95% CI of 1.08–1.90, and a p value of 0.013, once again highlighting the unique value of the level of GGT in the prediction of the risk of tumor recurrence [117]. The gene discussed is GGT1; the disease is neoplasm.
